Title: Polyimide optical wave plate and its production
Inventor: SAWADA TAKASHI
IPC: B29C71/02
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To easily produce a polyimide optical waver plate having excellent reliability against heat by uniaxially stretching a polyimide film while heating, in a method for the production of a polyimide optical wave plate including a process of uniaxially stretching a polyimide film. SOLUTION: First, a polar solution of a polyamide acid prepared from a tetracarboxylic acid or its derivative and diamine is applied on a proper substrate such as a silicon wafer by a spin coating method or the like, and heated to a specified temp. to perform thermal imidization. The atmosphere during the thermal imidization is not especially limited, but the process is preferably performed in an inert gas atmosphere such as nitrogen. Then the film is peeled from the substrate to produce a polyimide film, which is then uniaxially stretched to control the retardation while heating to produce the polyimide optical wave plate. The heating temperature in the uniaxial stretching process is preferably >=100 deg.C and lower than the glass transition temperature of the polyimide.

Abstract: PURPOSE:To permit heat sealing at the lower temp. in the shorter time than heretofore by using an adhesive agent consisting essentially of a polyamide resin to heat-seal a skirt and draw-out sheet to a photosensitive sheet. CONSTITUTION:Adhesive layers 30, 31 gravure-coated with an adhesive agent are formed on the fraw-out sheet 2.

The adhesive layers 32, 33 are formed to the top and bottom surface of the skirt 3 and the photosensitive sheet 1 is heat-sealed to one adhesive layer 33. The polyamide resin permits heat sealing with the substantial strength at the temp. lower than 140 deg.C, for example, 135 deg.C and in the shorter time, for example, 0.3 second. Since the thermal melting without pressure sensitiveness is made possible, the sheet 1 is free from fogging by pressure.
